ABSTRACT:
A biaxially oriented polyethylene terephthalate resin bottle-shaped container made by thermally crystallizing a neck portion of a preform, heating the preform, blow-molding the preform to form a primary intermediate molded bottle-shaped piece, raising the temperature of the primary intermediate molded bottle-shaped piece to a temperature greater than the temperature during blow-molding the preform to thermally contract the primary intermediate molded bottle-shaped piece to form a secondary intermediate molded bottle-shaped piece, and blow-molding the secondary intermediate molded bottle-shaped piece to form a bottle-shaped container.
